Racor themselves told me to do this once and I had to point out it was a massive safety issue and violated both ABYC and CFRs on a boat. My boat is gas powered, an ounce an hour leak could blow the boat up. Diesel seeping out will probably just make a smelly mess. Your filter now is essentially a water trap. The element will last forever.

My mechanic became a diesel expert working on diesel engines in Vietnam. I’m pretty sure he knows what he’s doing. The concern you raise in point 2, below, is likely why he installed an in-line filter before the electric pump.

The Racor does not care if fuel gets pushed in one end or pulled out the other end. Why it is a bad idea: 1. The filters are designed for vacuum side installation for safety. A leak will tend to suck air in and make the engine quit. A leak under pressure can seep or spray fuel and still leave enough to run the engine. This is really bad when the fuel is gasoline and not great for diesel. 2. The pump is now the first line of defense. Dirt/sand/algae/etc. can now clog the pump up and it is a lot harder to unclog a pump than a filter! Joe Della Barba Coquina C&C 35 MK I www.dellabarba.com<http://www.dellabarba.com>
